Prosessikäsittelyt

Prosessikäsittelyt refers to the management and manipulation of processes within a computer system. A process is an instance of a computer program that is being executed. Operating systems are responsible for managing these processes, allocating system resources such as CPU time, memory, and I/O devices to them.

Key aspects of prosessikäsittelyt include process creation and termination, process scheduling, inter-process communication (IPC), and process synchronization. Process creation involves starting a new program execution, while termination signifies the completion of a process. Scheduling determines the order in which processes get access to the CPU, using various algorithms to optimize throughput, response time, or fairness.

Inter-process communication allows different processes to exchange information and coordinate their actions. This can be achieved through mechanisms like shared memory, message passing, or pipes. Synchronization is crucial to prevent race conditions and ensure data integrity when multiple processes access shared resources. Synchronization primitives such as mutexes, semaphores, and monitors are used for this purpose.

Effective prosessikäsittelyt is fundamental for the smooth operation of any multitasking operating system, enabling efficient resource utilization and allowing users to run multiple applications concurrently. The complexity of prosessikäsittelyt often involves trade-offs between performance, resource consumption, and system stability.
